Researchers discover new gene for Sensenbrenner syndrome

Dutch researchers of the Radboud University Medical Center in Nijmegen found a new gene for Sensenbrenner syndrome (Journal of Medical Genetics, 2011 Mar 4). The mutation adds support to the hypothesis that defects in ciliar transport are the cause of the disease. Project leader Dr. Heleen H. Arts is supported by a Kolff Junior Postdoc Grant of the Dutch Kidney Foundation.

New study finds liver instead of the brain as source of Alzheimer’s plaques

Unexpected results from a Scripps Research Institute and ModGene, LLC study could completely alter scientists' ideas about Alzheimer's disease—pointing to the liver instead of the brain as the source of the "amyloid" that deposits as brain plaques associated with this devastating condition. The findings could offer a relatively simple approach for Alzheimer's prevention and treatment.

TCD announces first patient treated in its TCD-717 Phase I trial

Traslational Cancer Drugs Pharma, S.L. (“TCD”) announced today that the first patient was treated on Friday the 18th of February with TCD-717 in a Phase I study performed in patients with advanced solid tumors. TCD-717 is a first-in-class, small molecule that precisely inhibits Choline Kinase Alpha, an enzyme heavily involved in the carcinogenic process. A total of 30 patients are planned to be treated in the trial, which will be conducted in accordance with FDA approval, in two leading medical centers in the U.S. The Principal Investigators are Dr. Julie Brahmer at the Sidney Kimmel Comprehensive Cancer Center, Johns Hopkins Hospital in Baltimore; and Dr. Patricia LoRusso at the Barbara Ann Karmanos Cancer Institute in Detroit.

How Huntington's disease proteins move from cell to cell

One bad apple is all it takes to spoil the barrel. And one misfolded protein may be all that's necessary to corrupt other proteins, forming large aggregations linked to several incurable neurodegenerative diseases such as Huntington's, Parkinson's and Alzheimer's.

Researchers identify normal movement mechanisms of PrPC in brain

Researchers at the University of California, San Diego School of Medicine have identified the motors that move non-infectious prion proteins (PrPC) - found within many mammalian cells - up and down long, neuronal transport pathways.

Study explores role of proline containing peptides in inhibiting anti-apoptotic function of XIAP

Basic and translational research on cancer, and development of new cancer therapeutics, has focused on different aspects of cancer cellular function. One area of focus is the life and death of a cancer cell. Apoptosis, also known as programmed cell death, is a fundamental process of cells including cancer cells. The signal transduction pathways of apoptosis involve many different proteins and their interactions with each other.

Scientists generate beating heart cells from skin cells of young patients with severe genetic heart defect

Using skin cells from young patients who have a severe genetic heart defect, Stanford University School of Medicine scientists have generated beating heart cells that carry the same genetic mutation. The newly created human heart cells - cardiomyocytes - allowed the researchers for the first time to examine and characterize the disorder at the cellular level.
